Thanks that is what I needed!

I tried it, and indeed the links in captions are found, but something is
still not right. The :begin properties of the links in the caption seem
to be relative to the point after the : in the caption. That isn't
obvious and makes it hard to store a marker to the link. Is that
expected behavior?

* test links

#+caption: some text label:test3  cite:needs-1989-cal
| a | b |
| 1 | 3 |

 citenum:needs-1989-calcu

#+BEGIN_SRC emacs-lisp :results code
(org-element-map (org-element-parse-buffer) 'link
  (lambda (link)
    (cons
     (org-element-property :path link)
     (org-element-property :begin link)))
  nil nil nil t)
#+END_SRC
#+RESULTS:
#+BEGIN_SRC emacs-lisp
(("test3" . 11)
 ("needs-1989-cal" . 24)
 ("needs-1989-calcu" . 91))
#+END_SRC

(goto-char 11) This goes into the headline

(goto-char 24) This goes to the : in the caption

(goto-char 91)  This goes exactly where I expect
